72 Minutes Until the End of the World?

Carl Sagan’s conclusion is that the enemy is not a foreign nation, it’s the weapons themselves.

The generals that I refer to in that section on the SIOP [Strategic Integrated Operational Plan, the 1960s-era plan for general nuclear war] believed they could fight and win nuclear war, even if it meant killing 600 million people across the globe. That is insane. No one would argue that now.

A new book lays out the frighteningly fast path to nuclear Armageddon.

Nuclear war would be bad. Everyone knows this. Most people would probably rather not think through the specifics. But Annie Jacobsen, an author of seven books on sensitive national security topics, wants you to know exactly how bad it would be. Her new book Nuclear War: A Scenario, sketches out a global nuclear war with by-the-minute precision for all of the 72 minutes between the first missile launch and the end of the world. It’s already a bestseller.

It goes without saying that the scenario is fictional, but it is a journalistic work in that the scenario is constructed from dozens of interviews and documentation, some of it newly declassified, as a factual grounding to describe what could happen.

That’s this, in Jacobsen’s telling: A North Korean leader launches an intercontinental ballistic missile at the Pentagon, and then a submarine-launched ballistic missile at a nuclear reactor in California, for reasons beyond the scope of the book except to illustrate what one “mad king” with nuclear weapons could do. A harried president has a mere six minutes to decide on a response, while also being evacuated from the White House and pressured by the military to launch America’s own ICBMs at all 82 North Korean targets relevant to the nation’s nuclear and military forces and leadership. These missiles must fly over Russia, whose leaders spot them, assume their country is under attack (the respective presidents can’t get one another on the phone), and send a salvo back in the other direction, and so on until 72 minutes later three nuclear-armed states have managed to kill billions of people, with the remainder left starving on a poisoned Earth where the sun no longer shines and food no longer grows.

Some scholars, particularly among those who favor large nuclear arsenals as the best deterrent to being attacked with such weapons ourselves, have criticized some of Jacobsen’s assumptions. The U.S. wouldn’t have to court Russian miscalculation by overflying Russia with ICBMs when it has submarine-launched ballistic missiles in the Pacific. Public sources indicate that the president’s six-minute response window is still about in line with what Ronald Reagan noted with dismay in his memoirs. But that assumes he’s boxed into a “launch on warning” policy, something Jacobsen’s sources characterize as a constraint to move before enemy missiles actually strike, but which government policy documents insist is merely an option and not a mandate. (The president could also just decide, contra the deterrence touchstone of “mutual assured destruction,” not to nuke anybody at all in response.)

The book arrives at a time when the countries with the world’s largest nuclear arsenals, the U.S. and Russia, are violently at odds in Ukraine, a Russian state TV host is calling a Russia/NATO conflict “inevitable,” and the Council on Foreign Relations is gaming out scenarios in case the Russians use tactical nukes in Ukraine. Oh, and Iran is closer to a nuclear weapon than ever before. It’s a fair time to ask Jacobsen’s central question — what if deterrence fails? Even if we’d rather not think about it.

This conversation has been edited for length and clarity.

Kathy Gilsinan: The book starts with two missiles out of North Korea and ends with essentially the end of the world 72 minutes later. And the subtitle calls this “a scenario.” Is it a realistic scenario?

Annie Jacobsen: The scenario I chose was pieced together from interviews I did with 46 on-the-record sources and dozens of sources on background, and I ran by them various scenarios to come up with the most plausible scenario that unfolds once it begins. And this is what I came up with. And so far, I haven’t had anyone who actually runs these scenarios for NORAD take issue with the choices that I’ve made and the way in which the decision trees unfold, which makes it all the more frightening.

Gilsinan: Can you walk me through why it would be inevitable that the North Koreans hit us with two and we hit them back with 80?

Jacobsen: Let’s look at the words of General [John] Hyten, former STRATCOM commander, when he did an interview with CNN during former President Donald Trump’s “fire and fury” rhetoric days. And General Hyten said on the record, in a rather “don’t you dare” way, speaking almost directly to North Korea: “If somebody launches a nuclear weapon against us, we launch one back. They launch two, we launch two.”

To drill down a little bit further on that I looked to Dr. Bruce Blair, a former missileer himself. Now he’s deceased, but he became one of the world’s experts on nuclear command and control systems and authority. And he explained in a monograph I cite in the book that it’s far more likely that if North Korea hit the United with one missile, America would send 82 in return. [The monograph, written under the auspices of the anti-nuclear group Global Zero, points to about 80 “aimpoints” relevant to North Korea’s nuclear and other military forces as well as its leadership, but also notes that “graduated and flexible strikes” would be possible. Jacobsen says she relied on other sources to support the assumption the U.S. would attack all the targets.] Everything I did, I linked to an open-source scenario that had been thought through by experts who have dedicated their intellectual prowess to these issues for decades.

Gilsinan: In this scenario, the U.S. responds with ICBMs that have to fly over Russia, with predictable consequences. Why, according to the folks you’ve spoken to, would we risk flying missiles over a nuclear power if we could use submarine-launched missiles from the Pacific Ocean?

Jacobsen: I asked that same question to numerous people, and the most powerful answer came from former Secretary of Defense Leon Panetta himself: “There’s not a lot of thought given to who the hell else may be thinking about doing what … at a time like this.”

Gilsinan: Maybe this is the point of the book. I would like very much to believe that STRATCOM is smarter than me and has thought this through ahead of time.

Jacobsen: Part of the terrifying truth about nuclear war, or if a nuclear exchange were to unfold, is the insane time clock that was put on everything from the moment nuclear launch is detected. This is fact. And so is the fact that the president has only six minutes, that’s the rough time to make this decision. And in that time, the Black Book gets opened; he must make a choice from a counterattack list of choices inside the Black Book. Those choices have been thought through for multiple scenarios, but you can’t possibly take into consideration every contingency in real time, which makes so clear to readers exactly how insane the truth is about the unfolding of the scenario. And the unpredictability of it. And for example, one of the few people that actually read the contents of the Black Book and spoke to me about it in general terms so as not to violate security clearances is Ted Postol [a former assistant to the chief of naval operations]. He’s the one who said to me that every decision was a bad decision.

Gilsinan: Why do we think it’s six minutes specifically? I know that’s in Reagan’s memoirs, but why do we think that is still the case?
